Sealed Power pistons

Well all the CRs they list are for .030 motors. here's the specs they give you from Hughes Engines where i bought them from:
Pistons and Specs

the 167s are the second from the top, they'll sit .011 below deck on a stock deck block. if you are reusing the stock 318 heads, then you might want to got with the first one's on the page because if memory serves me correct the 318 heads from 68 have a really small chamber, you'll want to keep it under 10.5:1 for pump gas with cast iron heads.

I built a 318 with 340 small valve "j" heads, the 167 pistons, mopars .026" compressed gasket, and a stock bore and had a nice 9.5:1. That's with the heads chaved .010" and CCed at 69cc.

Cool on the 68 318. i didnt know they had that much torque stock! That's damn cool.
